131I-induced changes in rat thyroid gland function BJMBR
Torlak,V.; Zemunik,T.; Modun,D.; Capkun,V.; Pesutic-Pisac,V.; Markotic,A.; Pavela-Vrancic,M.; Stanicic,A..
Therapeutic doses of 131I administered to thyrotoxic patients may cause thyroid failure. The present study used a rat model to determine thyroid function after the administration of different doses of 131I (64-277 µCi). Thirty male Fisher rats in the experimental group and 30 in the control group (untreated) were followed for 6 months. The animals were 4 months old at the beginning of the experiment and were sacrificed at an age of 9 months. Hormone concentration was determined before 131I administration (4-month-old animals) and three times following 131I administration, when the animals were 7, 8, and 9 months old. The thyroid glands were removed and weighed, their volume was determined and histopathological examination was performed at the end of the...

Abscisic acid and the antioxidant system are involved in germination of Butia capitata seeds Acta Botanica
Bicalho,Elisa Monteze; Santos,Talita R. Silva dos; Garcia,Queila Souza.
ABSTRACT Seed germination is an important step for plants without vegetative propagation and is a physiological process that begins with specific environmental cues resulting in biochemical responses. Breaking-dormancy is necessary to study germination in dormant seeds with asynchronous germination. We investigated the processes of breaking dormancy and germination of Butia capitata (Arecaceae) seeds, in which germination is slow and asynchronous, by operculum removal. This treatment increased germination of B. capitata to 90 %. Embryos of dry, imbibed, 24-hours post-operculum removal and early-germinated seeds were collected for biochemical analysis of the following: quantification of abscisic acid (ABA) and hydrogen peroxide (H2O2), activities of...

Anti-Müllerian hormone (AMH) as a predictor of antral follicle population in heifers. Repositório Alice
CARDOSO, C. J. T; OLIVEIRA JUNIOR, J. S. de; KISCHEL, H.; SILVA, W. A. L da.; ARRUDA, E. D. da S.; CÁCERES, M. B. S.; OLIVEIRA, F. A. M. de.; NOGUEIRA, E.; NOGUEIRA, G. de P.; STERZA, F. de A. M..
Antral follicular population (AFP) and antiMüllerian hormone (AMH) concentration are strongly associated. Thus, analyzing AMH concentration is a reliable method to predict animals with high AFP, an important feature to select donor cows for embryos and oocytes. However, not much is known about this parameter in heifers, particularly in crossbred animals. The aim of this study was to assess AFP in heifers and cows and its relation to serum AMH levels. Bos taurus indicus cows (36?60-months-old; n = 30) and heifers (12?14-months-old; n = 17) of the same breed were evaluated. A single procedure of follicular counting was performed by ultrasound for each animal. Random sampling was performed to analyze serum AMH concentration. Cows showed higher AFP than...

De Conti, Daniela; Corredor-Prado, Jenny Paola; Roecker Junior, Djalma; Suzuki, Rogério Mamoru; Guerra, Miguel Pedro; Pescador, Rosete.
 Tissue culture techniques have been employed for orchid mass propagation by means of the morphogenetic route of protocorm like-bodies (PLBs). This study aimed to analyze and compare Indole-acetic acid (IAA) and sugar endogenous levels in protocorm-like bodies (PLBs) induction and development in Cattleya tigrina, in order to better understand this process and to optimize micropropagation procedure protocols. Leaves grown on MS (Murashige and Skoog) culture medium, suplemented with 9 μM TDZ for PLBs induction and development were collected after 0, 2, 7, 14, 30, 60 and 100 days of cultivation, for further analysis. Increase of IAA and reduction of sugar levels are strongly related to morphogenetic response, that is, PLBs formation over the preexisting ones...

Donnees cytologiques, electrophysiologiques et biochimiques relatives au phenomene de fecondation chez le homard (Homarus gammarus ). Implication du processus d'activation sur le mecanisme d'attache des oeufs pondus ArchiMer
Goudeau, M; Lachaise, F; Kubisz, P; Goudeau, H.
Electrophysiological measurements and related cytological controls were done on immature and submature oocytes of Homarus gammarus . By chromatography (HPLC) and radio-immunoassays (RIA) it was established that submature oocytes displayed different ecdysteroids. Furthermore, the structure of the stalk (funiculus) for the laid eggs attachment was analyzed. it consisted of the two superimposed vitelline envelopes which were likely modified by the cortical reaction exudate during the fertilization process. In addition, the successive secretory phases, regarding to the embryonic envelopes were evidenced. Finally, the ecdysteroid titers of embryonic stages were measured.

Effect of Egg Weight on External and Internal Qualities, Physiological and Hatching Success of Japanese Quail Eggs (Coturnix coturnix japonica) Rev. Bras. Ciênc. Avic.
Hegab,IM; Hanafy,AM.
ABSTRACT This experiment was conducted to evaluate the effect of egg weight and egg physical characteristics on embryonic development, hatchability, and hatchling weight of Japanese quails (Coturnix coturnix japonica). In total, 689 eggs were classified in two categories: small (<13.5 g) or large (≥13.5 g), and different external eggshell and internal quality traits were measured. On days 6 and 14 of incubation, tissue triiodothyronine (T3) and thyroxine (T4) were extracted from embryos in both egg sizes and analyzed. Relative to internal egg-quality traits, large eggs had significantly higher yolk height, yolk diameter, yolk weight, albumen height, and albumen weight than small eggs (p≤0.01). However, Haugh unit score (p=0.27) was not significantly...

Effects of hormonal priming on seed germination of pigeon pea under cadmium stress Anais da ABC (AABC)
SNEIDERIS,LARISSA C.; GAVASSI,MARINA A.; CAMPOS,MARCELO L.; D'AMICO-DAMIÃO,VICTOR; CARVALHO,ROGÉRIO F..
In this work we investigated whether priming with auxin, cytokinin, gibberellin, abscisic acid and ethylene, alters the physiological responses of seeds of pigeon pea germinated under water and cadmium stress. Seeds treated with water or non-treated seeds were used as control. Although compared to non-treated seeds we found that the hormone treatments improve the germination of pigeon pea under cadmium stress, however, these treatments did not differ from water. However, we also observed a trend of tolerance to the effects of cadmium in the presence of ethylene, suggesting that the use of this hormone may be an efficient method to overcome seed germination under metal stress.

Effects of Sodium Nitrate and Mixotrophic Culture on Biomass and Lipid Production in Hypersaline Microalgae Dunaliella Viridis Teod BABT
Kharati-Koupaei,Mansour; Moradshahi,Ali.
To access the potential application of Dunaliella viridis Teod. for biofuel production, the effects of culture media composition on biomass and lipid content of this microalgae were investigated. Measured at the 20 th day, sodium nitrate at 5.0 mM augmented biomass production by 26.5 percent compared to control (1 mM sodium nitrate). Total lipids expressed as µg mL-1 of culture also increased with increase in nitrate concentration up to 5.0 mM sodium nitrate, whereas when expressed on the per cell basis, total lipids stayed relatively constant at most of the tested nitrate concentrations except at 0.5 mM which was 31.4 percent higher compared to 1.0 mM nitrate. At 5.0 mM sodium nitrate, by using 20 g L-1 of glucose in mixotrophic culture of D. viridis,...
